ABDEC – Decipher the Writing of the Abb 🧠📘

More than 70 mind-blowing and page-transcending puzzles. ABDEC by Blaž Urban Gracar, published by Letibus Design, is a puzzle book for solo solvers – winner of a 2023 Thinky Award in the pen-and-paper puzzle category.

ABDEC is presented as a forgotten textbook about the writing system of the weird and elusive »Abb« creatures, whose typography resembles devilishly difficult packing puzzles. A fire burnt important pages in the book – the last remaining ABDEC in the world, scanned for this reissue – so you have to figure out how the writing system works completely on your own. From the creator of the critically acclaimed puzzle book LOK, ABDEC continues the same design philosophy of making the rules part of the puzzle, but takes it to the extreme. It is meant for thinky connoisseurs who want to explore ruleless puzzlescapes, and it offers a challenging but deeply rewarding solving experience. The book is spiral-bound and printed in full colour. On 88 pages you will find more than 70 puzzles, several secrets hidden in plain sight, plus hints, explained rules and solutions. A transparent sheet is included: place it over any page and draw on it with a dry-erase marker.
